Nhanganyaya kune Nheyo yeDiesel Majenareta

Mushure mokunge vharuvhu huru yeturbine yakavharwa, grid-yakabatana turbogenerator inoshanda seysynchronous motor, inotora simba rinoshanda uye ichikwevera turbine kuti itenderere, nokudaro ichigadzira reactive simba regadziriro.Nekuti vharuvhu hombe yeturbine yemhepo yakavharwa, iyo turbine muswe blade uye yakasara friction, kugadzira kukuvadzwa kwekuputika, kukuvadza kwekupisa mushure mekushanda kwenguva refu.Gasi nemvura turbines zvakare zvakanyanya kukuvadza prime mover. Jenareta reverse kuchengetedza simba rinonyanya kuchengetedza turbine kubva mukukuvadzwa.

Kumisikidzwa kweiyo steam turbine inverse kuchengetedza simba ndeyekuona kudzivirira chiito simba Pdz uye chiito kunonoka T.

1, Simba rekushanda re reverse simba rekudzivirira re turbogenerator rinogona kuverengwa sezvinotevera: Pdz =(krel * P1)/ηPdz- simba rekushanda re reverse simba rekudzivirira krel- reliability coefficient, tora 0.8 P1- simba rinoshandiswa ne iyo turbine kuchengetedza iyo synchronous kumhanya mushure mevhavha huru yakavharwa, Iyo ine hukama nechimiro uye kugona kweiyo steam turbine.Izvo zvakare zvine chekuita nechimiro cheiyo main steam system ye turbine jenareta (pipeline chimiro uye kana paine pombi dzekupfuura, nezvimwewo).Mumamiriro ezvinhu akajairwa, simba rakayerwa η re 1.5 ~ 2% (kushanda zvakanaka kana jenareta ichityaira jenareta returbine kutenderera) i0.98~0.99, saka :PDZ∑(1.2 ~ 1.6%) PN - iyo yakayerwa simba rejenareta.Muchokwadi, Pdz = 1-1.5% PN iri nani.

2, Kunonoka kwekuita .Kunonoka kwechiito kwejenareta inverse kuchengetedza simba kunofanira kuiswa maererano nenguva inobvumirwa kushanda yevhavha huru yekuvhara ye turbine jenareta.Nguva inobvumirwa kazhinji 10 ~ 15 maminitsi.Kuverengera uye mashandiro ekuita anoratidza kuti kana iyo steam turbine system ine bypass pombi, inotenderwa yekumhanya nguva yakareba.Nokudaro, kana kunonoka kwechiito chekudzivirira kwakagadzirirwa maererano nenguva yakabvumirwa yekumhanya mushure mokunge vharuvhu huru ye turbine yakavharwa, 5 ~ 10 maminitsi anogona kutorwa.Mushure mekuita, inoshandiswa kune demagnetization.

Pamusoro pezvo, mazhinji maturbogenerator ari mukushanda anoshandisa reverse kuchengetedza simba kuti atange akarongwa rwendo maseketi.Panguva ino, nguva yekuita inowanzotora 1 kusvika ku2s.Kune yakarongwa inverse kuchengetedza simba, nekuda kwenguva pfupi yekushanda, iyo chaiyo inverse simba inogona kunge iri diki nekuda kweiyo inertia yemhepo turbine uye jenareta munguva pfupi mushure mekuvharwa kwevhavha huru, saka iyo yakagadziriswa kukosha kweiyo inverse simba inofanira. haifaniri kudarika 1% PN.

Jenereta mugadziri musimboti sumo

Kana jenareta iine reverse simba (simba rekunze rinonongedza jenareta, kureva kuti jenareta rinova mota), reverse simba rinodzivirira chiito chedunhu chinotyora kubva pakugumburwa.Matatu echikamu magetsi uye maviri echikamu masaini masaini anoda kuunganidzwa.

Nekuda kwemhando dzakasiyana dzesimba rekutanga, majenareta akasiyana anogona kugadzirwa.Hydrogenerator inogona kugadzirwa kubva mumvura uye turbines.Nekuda kweakasiyana reservoir kugona uye kudonha, hydro-jenareta ane akasiyana kugona uye kumhanya anogona kugadzirwa.Uchishandisa marasha, oiri uye zvimwe zviwanikwa, ine boilers uye turbo-steam injini, steam turbine jenareta inogona kugadzirwa, kazhinji akakwira-kumhanya motors (3000rpm).Kune zvakare majenareta anoshandisa solar, mhepo, atomic, geothermal, tidal uye bioenergy.Mukuwedzera, nekuda kwemaitiro akasiyana ekushanda emajenareta, akakamurwa kuita DC jenareta, asynchronous jenareta uye synchronous jenareta.Majenareta makuru anoshandiswa zvakanyanya majenareta anowirirana.
